Study ObjectiveTo evaluate the effectiveness, safety, ease of placement, and ventilatory parameters of a new alternate airway device, the EasyTube® (EzT; Teleflex Ruesch, Research Triangle Park, NC), in comparison to the endotracheal tube (ETT).DesignProspective, randomized controlled trial.SettingUniversity Hospital.Subjects200 adult ASA physical status I and II patients scheduled for surgery.InterventionsPatients were randomized to two groups, one to receive ventilation via the EzT (n = 100) or the ETT (n = 100). After preoxygenation and induction with fentanyl and propofol, patients received muscle relaxation. The respective airway device was then inserted and mechanical ventilation was instituted.MeasurementsEase of insertion, number of insertion maneuvers, time until airtight seal of the airway was achieved, duration of surgery, leak pressure as well as arterial oxygen saturation (SpO2), and end-tidal carbon dioxide (ETCO2) data, were recorded.Main ResultsMallampati airway class was higher in the EzT group (P < 0.029), while thyromental distance showed no difference between the two groups. Ease of insertion was noted in the EzT group (P < 0.043). Number of insertions was equal in both groups; insertion time was shorter with the EzT (15.5 ± 3.6 sec vs. 19.3 ± 4.6 sec; P < 0.0001). Leak pressure and SpO2 were not significantly different, while ETCO2 was lower with the ETT (P < 0.024). Adjustments had to be made for two EzT group patients. No difference in frequency of laryngo-pharyngeal discomfort was observed in either group.ConclusionInsertion of an EzT appears to reduce time and facilitate placement of an airway device when compared with direct laryngoscopy and tracheal intubation. 相似文献

Effect of mild hypothermia on partial pressure of oxygen in brain tissue and brain temperature in patients with severe head injury 总被引:3,自引:0,他引:3
OBJECTIVE: To study the changes of partial pressure of oxygen in brain tissue (P(bt)O(2)) and brain temperature (BT) in patient s in acute phase of severe head injury, and to study the effect of mild hypothermia on P(bt)O(2) and BT. METHODS: The P(bt)O(2) and the BT of 18 patients with severe head injury were monitored, and the patients were treated with mild hypothermia within 20 hours after injury. The rectal temperature (RT) of the patients was kept on 31.5-34.9 degrees C for 1-7 days (57.7 hours+/-28.4 hours averagely), simultaneously, the indexes of P(bt)O(2) and BT were monitored for 1-5 days (with an average of 54.8 hours+/-27.0 hours). According to Glasgow Outcome Scale (GOS), the prognosis of the patients was evaluated at 6 months after injury. RESULTS: Within 24 hours after severe head injury, the P(bt)O(2) was significantly lower (9.6 mm Hg+/-6.8 mm Hg, 1 mm Hg=0.133 kPa) than the normal value (16-40 mm Hg). After treatment of mild hypothermia, the mean P(bt)O(2) increased to 28.7 mm Hg+/-8.8 mm Hg during the first 24 hours, and the P(bt)O(2) was still maintained within the range of normal value at 3 days after injury. The BT was higher than the RT in the patients in acute phase of severe head injury, and the difference between the BT and the RT significantly increased after treatment of mild hypothermia. Hyperventilation (the partial pressure of carbon dioxide in artery (P(a)CO(2)) approximately 25 mm Hg) decreased the high intracranial pressure (ICP) and significantly decreased the P(bt)O(2). CONCLUSIONS: This study demonstrates that P(pt)O(2) and BT monitoring is a safe, reliable and sensitive diagnostic method to follow cerebral oxygenation. It might become an important tool in our treatment regime for patients in the acute phase of severe head injury requiring hypothermia and hyperventilation. 相似文献

Background
We present the results of a prospective series of 60 patients treated for neuromuscular spinal deformities with an original spinopelvic construct using two sacral screws and two iliac screws. Clinical and radiological results obtained with this new surgical technique were studied and discussed according to the epidemiological data and relevant literature.Methods
From January 2008 to June 2010, the clinical data of every patient who underwent spinopelvic fixation for treatment of a neuromuscular spinal deformity were recorded prospectively.Results
Sixty patients were operated on during the study period. Spinal correction and fusion was performed by posterior approach. In six patients with a residual spinopelvic imbalance more than 15° on lateral preoperative bending films, an anterior release of the thoracolumbar junction was performed on the same day, before posterior correction. Preoperative pelvic obliquity (PO) ranged from 4° to 44° (mean 21.6°). Postoperative pelvic obliquity ranged from 0° to 14 (mean 4.6°). No significant loss of correction was noted at the last follow-up. One patient died 3 months after the initial procedure due to respiratory compromise. 11 patients had early postoperative infections of the posterior approach.Conclusions
Despite a high rate of infectious complications, optimal correction of pelvic obliquity requires extension of spinal instrumentation to the pelvis. Spinopelvic fixation remains a difficult challenge in neurological patients with hypotrophy. We think that pelvic fixation with the “T construct” did provide effective and improved spinal stabilization in these patients, while reducing the need for a postoperative cast or brace. As a result, patients had a favourable postoperative course with early mobilization and return to a comfortable sitting position. 相似文献15.
